Library from site and from program don’t works
Simulator does not have LCD (or buttons, or POTs, or LEDs, etc.), so you cannot use those nodes when running a simulation. You can replace the LCD display with a watch node to see what text would be displayed on the LCD. You can also replace buttons, POTs, and other input devices with tweak-* nodes (tweak-pulse, tweak-number, etc. depending on what you want to input).
